ROBERT ELMER MOCK, OF LAHOMA, OKLAHOMA TERRITORY.

CHAlR-BRACE.

SPECIFIGATION forming part of Letters Patent No. 752,243, dated February 16, 1904:. Application filed June 22, 1903. Serial No. 162,588. (No-model.)

citizen of the United States, residing at La homa, in the county of Garfield and Territory of Oklahoma, have invented a new and useful Improvement in Chair-Braces, of which the following is a specification.

My invention relates to chair-braces, and has for its object to produce a device of this character of comparatively simple construction which will be efficient in operation, one which will eflectually prevent looseness and rattling or spreading of the chair-legs, and one which may be readily adjusted for chairs of varying sizes or styles.

To these ends the invention comprises the novel details of construction and combination of parts more fully hereinafter described.

In the accompanying drawings, Figure 1 is a perspective View of a chair having my improved brace applied thereto. Fig. 2 is a side elevation partly broken away. Fig. 3 is 'a horizontal sectional plan on the line 3 3 of Fig. 2.

Referring to the'drawings, '1 indicates a chair-bottom, 2 its sustaining legs, and 3 the rungs connecting the legs. These parts may be of any suitable or desired material and construction and assembled as usual by inserting the upper ends of the legs in sockets formed in the chair-bottom and the ends of the rungs in similar sockets with which thelegs are provided.

My improved brace comprises a tension member 4: and connecting elements 5. The tension member is preferably in the form of a turnbuckle, the opposite screws of which are provided at their outer ends with eyes 6, to which the inner ends of the connecting elements are attached. The connecting-elements 5 consist, preferably, each of a length of rodiron having formed at its inner end an eye 7, which engages'the eye 6 of the tension memher, and at its outer end a substantially semicircular hook 8, which engages the legs 2 of the chair, the hook being provided with an inwardly-extending tooth or point 9, adapted to engage or bite into the material of the ob airleg and prevent slipping of the parts relatively.

The brace is connected with the chair-bottom by means of a pair of hangers or connecting members 10 10, attached to the lower face of the bottom one adjacent to the front and the other to the rear thereof at substantially its transverse center. These hangers each comprise a hook 11, which detachably engages a screw-eye 12, attached to the chair, an eyerod 13, and adjustable devices 14, connecting the eye-rod and hook. The eye-rod 13 consists, preferably, of a length of heavy-gage wire provided at one end with an eye 15, through which one 'of thescrews of the turnbuckle passes, and at its opposite end with a similar eye 16, engaged by theadjustable device l l, which is preferably in the form of a short length of chain, any one of the links of which may be engaged with an eye 17, formed upon the normally lower end of the hook 11 and having an opening to one side to allow engagement or disengagement of the chain-links therewith, thus permitting ready adjustment of the hanger 10 to accord with the length of the chair-legs or to bring the brace to any suitable point thereon.

In practice when the parts are properly engaged with the chair the hangers 10 may be adjusted for elevating the tension member 4 somewhat above the point of engagement of the connecting elements 5 with the chair-legs, as illustrated more clearly in Fig. 2, thus imparting to the connecting elements a slight upward inclination from their point of attachment with the chair-legs to their point of engagement with the tension member, the hangers 10 being at the same time inclined slightly inward from their point of attachment with the chair-bottom to their point of engagement with the tension member. Thus when the tension member is manipulated for placing the connecting elements under tension the latter will exert an inward and slightly upward pull upon the chair-legs, while at the same time the hangers 10 will be placed under tension and exert an upward pull upon the tension member, whereby the direct-ion of pull upon the various parts of the chair will be such as to hold the ends of the rungs 3 firmly in the.

bottom, thus effectually preventing looseness and rattling of the parts and spreading of the legs. It is to be particularly noted that my device is adapted for attachment to any style of chairs and that when applied to cane-seat chairs there will be no mechanism lying directly beneath the cane seat; also, that the hangers may be quickly adjusted, according to the length of the chair-legs, by engaging any desired link of the adjusting chain or device 14: with the eye 17 in order to maintain the tension member at the desired elevation for exerting the pull in the proper direction upon the connecting elements.

From the foregoing it will be seen that I produce a device of simple construction which may be readily adapted to chairs of various sizes and styles and one which in practice efliiciently perform its functions, and in attaining these ends it is to be understood thatIdo not limit myself to the precise details herein shown and described, inasmuch as minor changes may be made therein without departing from the spirit of my invention.

Having thus described my invention, What I claim is 1. In a device of theclass described, the combination with a chair, of a pair of hangers attached to the chair-bottom and each comprising a rod provided at its lower end with an eye, a hook, a chain adjustably connecting the hook and rod, a horizontally-disposed tension member sustained by the hangers, and connecting elements attached to the tension member and engaging the chair-legs each at a point below the tension member.

2. In a device of the class described, the combination with a chair, of a pair of hangers attached to the chair-bottom adjacent to its opposite edges and each comprising a rod provided at its lower end with an eye, a hook and a chain adjustably connecting the hook, rod,

a horizontally-disposed turnbuckle sustained by the hangers and having opposite screws extended through the eyes of the hangers, and connecting elements attached to the turnbuckle and engaging the chair-legs each at a point below the turnbuckle.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.

ROBERT ELMER MOCK.
